operation. Itprovides general-purpose remote I/O expansion for most microcontroller families via the I
2
C interface [serial clock(SCL), serial data (SDA)].
The PCA9535 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and PolarityInversion (active-high or active-low operation) registers. At power on, the I/Os are configured as inputs. Thesystem master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data foreach input or output is kept in the corresponding Input or Output Port register. The polarity of the Input Portregister can be inverted with the Polarity Inversion register. All registers can be read by the system master.
The system master can reset the PCA9535 in the event of a timeout or other improper operation by utilizing thepower-on reset feature, which puts the registers in their default state and initializes the I
2
C/SMBus state machine.
The PCA9535 open-drain interrupt ( INT) output is activated when any input state differs from its correspondingInput Port register state and is used to indicate to the system master that an input state has changed.
INT can be connected to the interrupt input of a microcontroller. By sending an interrupt signal on this line, theremote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate viathe I
2
C bus. Thus, the PCA9535 can remain a simple slave device.

The device outputs (latched) have high-current drive capability for directly driving LEDs. The device has lowcurrent consumption.
Although pin-to-pin and I
2
C address compatible with the PCF8575, software changes are required due to theenhancements.
The PCA9535 is identical to the PCA9555, except for the removal of the internal I/O pullup resistor, which greatlyreduces power consumption when the I/Os are held low.
Three hardware pins (A0, A1, and A2) are used to program and vary the fixed I
2
C address and allow up to eightdevices to share the same I

SIMPLIFIED SCHEMATIC OF P-PORT I/Os
(1)
(1) At power-on reset, all registers return to default values.
When an I/O is configured as an input, FETs Q1 and Q2 are off, which creates a high-impedance input. Theinput voltage may be raised above V
CC
to a maximum of 5.5 V.
If the I/O is configured as an output, Q1 or Q2 is enabled, depending on the state of the Output Port register. Inthis case, there are low-impedance paths between the I/O pin and either V
CC
or GND. The external voltageapplied to this I/O pin should not exceed the recommended levels for proper operation.

The bidirectional I
2
C bus consists of the serial clock (SCL) and serial data (SDA) lines. Both lines must beconnected to a positive supply via a pullup resistor when connected to the output stages of a device. Datatransfer may be initiated only when the bus is not busy.
I
2
C communication with this device is initiated by a master sending a Start condition, a high-to-low transition onthe SDA input/output while the SCL input is high (see Figure 1 ). After the Start condition, the device address byteis sent, MSB first, including the data direction bit (R/W). This device does not respond to the general calladdress.
After receiving the valid address byte, this device responds with an ACK, a low on the SDA input/output duringthe high of the ACK-related clock pulse. The address inputs (A0 A2) of the slave device must not be changedbetween the Start and Stop conditions.
On the I
2
C bus, only one data bit is transferred during each clock pulse. The data on the SDA line must remainstable during the high pulse of the clock period, as changes in the data line at this time are interpreted as controlcommands (Start or Stop) (see Figure 2 ).
A Stop condition, a low-to-high transition on the SDA input/output while the SCL input is high, is sent by themaster (see Figure 1 ).
Any number of data bytes can be transferred from the transmitter to the receiver between the Start and the Stopconditions. Each byte of eight bits is followed by one ACK bit. The transmitter must release the SDA line beforethe receiver can send an ACK bit. The device that acknowledges must pull down the SDA line during the ACKclock pulse so that the SDA line is stable low during the high pulse of the ACK-related clock period (seeFigure 3 ). When a slave receiver is addressed, it must generate an ACK after each byte is received. Similarly,the master must generate an ACK after each byte that it receives from the slave transmitter. Setup and holdtimes must be met to ensure proper operation.
A master receiver signals an end of data to the slave transmitter by not generating an acknowledge (NACK) afterthe last byte has been clocked out of the slave. This is done by the master receiver by holding the SDA line high.In this event, the transmitter must release the data line to enable the master to generate a Stop condition.

The last bit of the slave address defines the operation (read or write) to be performed. A high (1) selects a readoperation, while a low (0) selects a write operation.
Following the successful acknowledgment of the address byte, the bus master sends a command byte that isstored in the control register in the PCA9535. Three bits of this data byte state the operation (read or write) andthe internal register (Input, Output, Polarity Inversion, or Configuration) that will be affected. This register can bewritten or read through the I
2
C bus. The command byte is sent only during a write transmission.
Once a command byte has been sent, the register that was addressed continues to be accessed by reads until anew command byte has been sent.

The Input Port registers (registers 0 and 1) reflect the incoming logic levels of the pins, regardless of whether thepin is defined as an input or an output by the Configuration Register. It only acts on read operation. Writes tothese registers have no effect. The default value, X, is determined by the externally applied logic level.
Before a read operation, a write transmission is sent with the command byte to let the I

C device know that theInput Port registers will be accessed next.

The Output Port registers (registers 2 and 3) show the outgoing logic levels of the pins defined as outputs by theConfiguration register. Bit values in this register have no effect on pins defined as inputs. In turn, reads from thisregister reflect the value that is in the flip-flop controlling the output selection, not the actual pin value.

The Polarity Inversion registers (registers 4 and 5) allow polarity inversion of pins defined as inputs by theConfiguration register. If a bit in this register is set (written with 1), the corresponding pin's polarity is inverted. If abit in this register is cleared (written with a 0), the corresponding pin's original polarity is retained.

If a bit in this register isset to 1, the corresponding port pin is enabled as an input with a high-impedance output driver. If a bit in thisregister is cleared to 0, the corresponding port pin is enabled as an output.

An interrupt is generated by any rising or falling edge of the port inputs in the input mode. After time, t
iv
, thesignal INT is valid. Resetting the interrupt circuit is achieved when data on the port is changed to the originalsetting or data is read from the port that generated the interrupt or in a Stop event. Resetting occurs in the readmode at the acknowledge (ACK) bit or not acknowledge (NACK) bit after the falling edge of the SCL signal.Interrupts that occur during the ACK or NACK clock pulse can be lost (or be very short) due to the resetting ofthe interrupt during this pulse. Each change of the I/Os after resetting is detected and is transmitted as INT.
Reading from or writing to another device does not affect the interrupt circuit, and a pin configured as an outputcannot cause an interrupt. Changing an I/O from an output to an input may cause a false interrupt to occur, if thestate of the pin does not match the contents of the Input Port register. Because each 8-bit port is readindependently, the interrupt caused by port 0 is not cleared by a read of port 1, or vice versa.
INT has an open-drain structure and requires a pullup resistor to V
CC
.
Data is exchanged between the master and the PCA9535 through write and read commands.
Data is transmitted to the PCA9535 by sending the device address and setting the least-significant bit to a logic 0(see Figure 4 for device address). The command byte is sent after the address and determines which registerreceives the data that follows the command byte.
The eight registers within the PCA9535 are configured to operate as four register pairs. The four pairs are InputPorts, Output Ports, Polarity Inversions, and Configurations. After sending data to one register, the next data byteis sent to the other register in the pair (see Figure 6 and Figure 7 ). For example, if the first byte is sent to OutputPort 1 (register 3), the next byte is stored in Output Port 0 (register 2).
There is no limitation on the number of data bytes sent in one write transmission. In this way, each 8-bit registermay be updated independently of the other registers.

The bus master first must send the PCA9535 address with the least-significant bit set to a logic 0 (see Figure 4for device address). The command byte is sent after the address and determines which register is accessed.After a restart, the device address is sent again, but this time, the least-significant bit is set to a logic 1. Datafrom the register defined by the command byte then is sent by the PCA9535 (see Figure 8 through Figure 10 ).
After a restart, the value of the register defined by the command byte matches the register being accessed whenthe restart occurred. For example, if the command byte references Input Port 1 before the restart, and the restartoccurs when Input Port 0 is being read, the stored command byte changes to reference Input Port 0. The originalcommand byte is forgotten. If a subsequent restart occurs, Input Port 0 is read first. Data is clocked into theregister on the rising edge of the ACK clock pulse. After the first byte is read, additional bytes may be read, butthe data now reflect the information in the other register in the pair. For example, if Input Port 1 is read, the nextbyte read is Input Port 0.
Data is clocked into the register on the rising edge of the ACK clock pulse. There is no limitation on the numberof data bytes received in one read transmission, but when the final byte is received, the bus master must notacknowledge the data

When an I/O is used to control an LED, normally it is connected to V
CC
through a resistor as shown in Figure 15 .Because the LED acts as a diode, when the LED is off, the I/O V
IN
is about 1.2 V less than V
CC
. The ΔI
CCparameter in Electrical Characteristics shows how I
CC
increases as V
IN
becomes lower than V
CC
. Forbattery-powered applications, it is essential that the voltage of I/O pins is greater than or equal to V
CC
, when theLED is off, to minimize current consumption.
Figure 16 shows a high-value resistor in parallel with the LED. Figure 17 shows V
CC
less than the LED supplyvoltage by at least 1.2 V. Both of these methods maintain the I/O V
IN
at or above V
CC
and prevent additionalsupply-current consumption when the LED is off.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
